Specification of Letters Patent.

Patented Nov.. 27, 191'?.

Application filed January 22, 1917. Serial 1\T o. 143,774.

To all 107mm t may concern:

Be it known that I, JOHN H. MARSH, a citizen of the United States, residing at Oshkosh, in the county of Winnebago, State of Wisconsin, have invented certain new and useful Improvements in Devices for Stretching Wire-Fabric Bed-Springs; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in devices for stretching wire fabric bed springs, and has for its object to s0 construct a device of this character' that it can be readily applied to the spring frame of a bed so as to stretch the wire fabric to the desired tension.

A further object of the invention is to provide a device of this character constructed in such a manner that it can be easily and quickly operated to stretch the spring'.

With these and other objects in View, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, ciaimed and illustrated in the accompanying drawing, in which Figure 1 is a top plan view of the device showing it in use.

Fig. 2 is a side elevation thereof.

Fig. 3 is a sectional view on line 3-3 of Fi 1.

Fig. 4 is a sectional view on line 4-4 of Fi 1.

Fig. 5 is a sectional view on line 5 5 of Fif.

eferring to the drawing 1 indicates the spring frame which comprises side bars 2 and end bars 3, said end bars having assoc'iated therewith the clamping bars 4 which serve to grip the ends of the wire fabric Spring 5.

The stretcher comprises a bar 6, said bar having secured to its under surface spaced castings 7, said castings having threaded bores 8 formed therein for engaging the threaded shafts 9, the outer ends of which are provided with transverse heads 10, said heads being provided with sleeves 11 for receiving the rods 12. By providing the rods 12 the shafts can be rotated with comparative ease.

The inner ends of the shafts 9 are engaged in the adjacent ends of the tubes 13, and bear against the bolts 14 which are disposed transversely through the tubes. The tubes are further provided with perforations 15, the purpose of which will appear later.

A bar 1G is provided and has its ends provided with vertically spaced plates 17, said plates having registered openings 18 formed therein so that pins 19 can be engaged therein and with selected openings 15 formed in the tubes.

The bar 6 is provided with a zig-Zag row of spurs 20 which are adapted to engage the fabric spring 5 so that when the shafts 9 are rotated in one direction the bar 6 will move outwardly, while the bar 16 which is engaged against the adjacent bar 3 of the frame 1 will remain stationary. It will be understood that when the fabric is being stretched that the bar 4 adjacent the bar 6 remains engaged with the adjacent bar 3, and after the fabric has been stretched to the desired tension the bar is removed and the fabric stretched further with pliers or the like, and is then stapled to the adjacent bar 3. After this has been done the fabric is cut off even with the bar 3 and the bar is replaced so as to hold the fabric firmly gripped.

From the foregoing description it will be seen that a device has been provided which is extremely simple in construction, and one which can be readily placed in operative relation to the frame 1 upon simply placing the bar 16 against one of the bars 3 of the frame, while the spurs 20 can be quickly engaged with the fabric spring 5, after which the shafts 9 are rotated to stretch the fabric to the desired tension.
